MCTIP labs in Virtualbox or VMWare using Pfsense as router assistance needed

[fkane17]

I am trying to practice for the MCTIP Enterprise 2008. I am expecting to use Virtualbox or VMWare workstation 8 to do all the lab.
My goal to simulate an Active Directory Network with 3 sites that have the following subnets:

Dakar: Network 192.168.10.0 /24. 2 DC, 1 member server and 500 workstations client Win7.
Thies : Network 192.168.12.0 /24. 2 DC, 1 member server and 400 workstations client Win7.
St Louis: Network 192.168.14.0 /24. 2 DC, 1 member server and 300 workstation client Win7.

I installed pFsense, WAN is 192.168.1.10 (DHCP from my router), LAN 192.168.10.1
I created 3 VLANS, VLAN10 192.168.10.2, VLAN20 192.168.12.1, VLAN30 192.168.14.1

I can ping using pfsense option 7 any IP listed above.
But when I logon to the Virtual machines I created I can only ping within the same VLANS(for example DC1 and DC2 in VLAN10 can ping each other)
But DC1 in VLAN10 cannot ping the DCs in VLAN20 or VLAN30.
I disabled NAT rule and Firewall in Pfsense.

What Am I doing wrong ?

Any default gateway set on the VMs?
By default there is a deny rule on all new interfaces, start with adding allow all to all rules on all VLANs
